Hand-Picked Comparisons
Nessus Professional 10.11
The industry leader for vulnerability scanning, trusted by over 30,000 organizations. The late 2025 update (v10.11.1) features native support for Windows Server 2025, macOS 16, and RHEL 10. It includes global scan timeout controls and enhanced air-gapped web application scanning. While it boasts the lowest false-positive rate and the largest vulnerability database in the industry, the high annual cost and restricted free tier have made it less accessible for individual consultants.
Nessus Professional (v11.x Agentic AI)
The industry's most widely deployed vulnerability scanner, now featuring Agentic AI for autonomous task execution and proactive risk triage. Version 11 (2025/2026) offers the industry's lowest false-positive rate and coverage for 200,000+ plugins. While its accuracy is unmatched, its high annual cost and lack of a centralized dashboard for managing multiple scanners make it restrictive for growing teams.
